Synopsis
Cold front exits eastern mountains this morning. High pressure builds
providing dry conditions. Cooler Sunday through Tuesday, with
upper level disturbances possibly providing a few light showers.

Near term through tonight
As 630 am Saturday...

previous forecast remains on track. No changes necessary.

As of 430 am Saturday...

rainfall has diminished or moved out of the area. Sent a quick
update to cancel the flash flood watch. Rest of forecast remains
on track.

As of 320 am Saturday...

sfc analysis and radar images show the cold front moving east
across WV to reach the eastern mountains by sunrise. Meanwhile,
light rain will accompany the cold front with very little change
in temperatures. High pressure ridge builds along the oh river
through tonight. This high pressure will bring dry and fresh
air mass to the area.

A flash flood watch will probably be allow to expire at 6 am.

Some creeks and rivers are still running high and some are
above flood stage especially in northeast ky due to recent
rainfall. A river flood warning remains in effect for the little
sandy river at grayson as it remains above flood stage.

Short term Sunday through Tuesday night
As of 445 am Saturday...

reinforcing shots of progressively cooler air arrive this
period, on a series upper level short wave troughs that act to
deepen the long wave trough position over the eastern u.S. The
final short wave may finally be able to summon enough moisture
for a shower or thunderstorm north come Tuesday.

Canadian high pressure builds in for the finale... As the nadir
of this cool spell is reached under clear, calm conditions
Wednesday morning.

Long term Wednesday through Friday
As of 445 am Saturday...

this period begins with an increase in temperature and moisture,
as an upper level long wave trough over the eastern u.S., moves
off to the east. With the upper level high over the
southwestern u.S. Backing away, the upper level flow flattens.

Increasing moisture in a return low level south to southwest
flow around the surface high exiting to the east, and weak upper
level short wave troughs in the flattening flow, will increase
the chance for mainly afternoon and evening showers and
thunderstorms Thursday and especially Friday.

A stronger upper level short wave trough and surface frontal
system will bring a better chance for less diurnally driven
showers and thunderstorms next Saturday.

Central guidance temperatures accepted, which show warming and
then leveling off above normal, especially at night.

Aviation 10z Saturday through Wednesday
As of 615 am Saturday...

cold front crossed the eastern mountains this morning. A low
strato deck around 500 feet continues with ifr conditions at
crw and bkw, and MVFR ceilings at ckb and ekn sites. Conditions
will improve around 13-14z when the mixing lift off the low
clouds providing with widespreadVFR conditions today.

High pressure builds from the west to bring some clearing
spreading from west to east today. However, diurnal CU can be
expected during the afternoon hours.

Areas of ifr lifr fog will be possible along river valleys and
areas that received rainfall late tonight into Sunday morning.

Forecast confidence and alternate scenarios through 12z Sunday...

forecast confidence: medium.

Alternate scenarios: duration of MVFR ifr conditions may vary
from forecast.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
